Installed BD Diesel 2 Low Kit
Hello all. My 2013 Ram 3500 has a 6 speed manual transmission and with the Laramie package, the 4x4 system automatically engages the transfer case and hubs at the turn of a dial on the dash. This sy...

On our TV, the issue is not excessive engine torque. It is the 4WD driveline design.
Your front and rear diffs have, er, differentials. The purpose of those is to allow the L/R wheels to turn at different rates. But our transfer cases (in part time 4WD systems in the big three HD trucks) do not have any differential system. The F/R driveshafts are positively locked together with a heavy chain. But F/R wheels are still rotating at different rates, and at least one tire must slip on the ground. If on hard surfaces like pavement, that cannot easily slip.
Your front driveline is much less robust than the rear. It is not designed to handle that kind of low range torque. So you break front drive shaft, or axle shaft, U-joints. Or you break the front output flange on your transfer case.
Most of the pics you find online will be the result of putting too much torque to the ground, especially off-roading stuff. Not really a 4WD on pavement scenario. Those guys are kind of proud of breaking stuff. But don't kid yourself and assume it can't happen to you. That torque that is backdriving your steering wheel and jerking the wheel out of your hands, is more than harsh enough to break things. Hard turns in low range are the worst.
